Abstract

According to the flame-retardant and anti-aging cover plate for the spare tire of the car trunk and the preparation method of the flame-retardant and anti-aging cover plate, during actual application, shape cutting is conducted on the cover plate through punching, at the moment, the edge of the cover plate is sharp, potential safety hazards exist during application, and therefore in actual application, the cover plate can be subjected to outer-layer fabric wrapping protection, and the service life of the cover plate is prolonged. The cover plate is prevented from being broken and layered after the edge of the cover plate is collided; during fabric coating, polyurethane hot melt adhesive is sprayed and then pressed and coated to form outer fabric coating, the coated cover plate is put into practical application, and the cover plate is installed in a luggage case and used for separating a spare tire bin from the luggage case, so that the effect of shielding spare tires and articles can be achieved. In order not to influence the foaming effect of the polyurethane foaming layer, the content of the titanium dioxide flame retardant and the content of the graphene oxide flame retardant are adjusted and limited, the performance indexes such as light weight, odor and flame retardance of the prepared trunk spare tire cover plate all meet the requirements, and the trunk spare tire cover plate has excellent ultraviolet aging resistance and high applicability.

Description

technical field [0001] The invention relates to the technical field of a spare tire cover, in particular to a flame-retardant and aging-resistant cover for a spare tire in a trunk of an automobile and a preparation method thereof. Background technique [0002] The spare tire cover is generally installed in the trunk in practical application, and is used to separate the spare tire compartment and the trunk, and can realize the function of covering the spare tire and objects. It has a wide range of existing applications; the spare tire cover is more commonly used today The board materials include PP injection molding, PP honeycomb board, hard fiber board, etc., but the above materials all have the disadvantages of poor flame retardancy and low strength, and the load-bearing performance cannot meet the practical application. [0003] Based on this situation, in order to improve the flame retardancy and load-bearing performance of the spare tire cover, this application discloses...
